FIELD OF THE INVENTION

This invention relates to the treatment of antibiotic-resistant infections, including particularly infections caused by bacteria, Mycobacteria and fungi. A preferred group of compositions of the invention contain as active agents compounds containing pyridyl, quinolyl or benzoquinolyl ring systems substituted on the nitrogen-containing ring at the carbon oposite the nitrogen by a carbon bound to an oxygen which is also bound to a nitrogen through a saturated carbon or carbon chain, or, in the case of the pyridyl ring system, the substituent at the 4 position of the pyridyl ring may be an alkyl which may be substituted with halo, hydroxy, alkoxy, amino or alkylamino.

BACKGROUND OF THE INVENTION

The benefit from use of antibiotics as a means of treating infections has been increasingly compromised by the development of resistant strains of microorganisms. Most of the new drugs are derivatives of older compounds. It is necessary to develop new agents that will respond to the current needs for medicinals that will effectively control pathogenic microbial populations that are resistant to antibiotics.

Mefloquine is quinolyl compound having two trifluoromethyl groups attached to the quinolyl ring. This compound has been used to treat malaria. It has also been found to have some activity against bacterial pathogens in vitro.

SUMMARY OF THE INVENTION

This invention comprises compositions containing as active agents compounds which have pyridyl or quinolyl ring systems (including benzoquinolyl ring systems) substituted at the carbon opposite the nitrogen by a carbon bound directly to an oxygen and to a nitrogen through a saturated carbon or carbon chain or, in the case of pyridyl, an alkyl, alkenyl, alkyloxy, alkenyloxy, amino or alkylamino group ehrein alkyl has 1-6 carbons, alkenyl has 2-6 carbons, wherein said alkyl or alkenyl groups may, optionally, have amino, hydroxy or halo substituents. Preferred compounds of the invention are those wherein the quinolyl ring system has at least one electron-rich substituent on the quinolyl ring system, including, for example, halo, phenyl, hydroxy, alkoxy or trihalomethyl substituents and the substituent at the carbon directly opposite the nitrogen atom is of the structure --CHOZX wherein Z may be a second bond to the oxygen or may be carboxyl, ether or ester moiety wherein the ether or ester moiety may be alkyl of 1-8 carbons, phenyl, phenylalkyl wherein the alkyl moiety consists of 1-4 carbons and wherein any said alkyl or phenyl group may, additionally, be substituted with hydroxy, alkyl of 1-2 carbons, alkenyl of 2-3 carbons, halo, amino, or alkyl amino group, X is CH₂ N((CH2)_(n) (CH₃)_(m) wherein n is ≦5, m is 1 or 2 with the proviso that when m is 2, n is ≦3, or X may be CH₂ N(CH₂)_(q) wherein q may be up to 10, which is cyclized and may have up to 4 brige carbons or X is a saturated six-member nitrogen containing ring which may be substituted, wherein the piperidinyl moiety is bound through the carbon at the 2 position of the ring to the CHOZ through a carbon atom. The six member ring may have 1-4 bridge carbons to produce complex ring systems such as quinuclidinyl ring systems.

The active agents are useful for treating patients suffering from infections including gram positive bacteria, gram negative bacteria, fungi and mycobacterium. They are effective against strains which have shown resistance to other antimicrobial agents.

DETAILED DESCRIPTION OF THE INVENTION

It has been found that compositions of the following formula:

    A-B-N-Z(n)

wherein N is a quinolyl, pyridyl or benzoquinolyl rings substituted at the carbon opposite the nitrogen on the nitrogen-containing ring by B-A wherein B is a carbon (C') bound to an oxygen, (50 O, OH, Oalk, OCOalk, OCOaryl, OCOphenyl alkyl, or an oxygen in a cyclic moiety wherein aryl is phenyl or naphthyl and alkyl has 1-4 carbons and may be substituted hydroxy, or with 1-2 halo atoms) and wherein said carbon C' is also bound to a saturated carbon which is bond directly to a nitrogen-containing saturated chain or nitrogen-containing saturated ring system (for example, piperidinyl or quinuclidinyl ring systems), wherein any saturated ring system may be substituted with alkyl, alkenyl, halo, alkoxy or haloalkyl moieties of 1-5 carbons or with phenyl, phenoxy, phenylalkyl, phenylalkoxy, carboxy or carbonyl groups, wherein the carboxy or carbonyl groups, including keto or ester moieties with alkyl groups of 1-4 carbons, alkenyl groups of 2-5 carbons or phenylalkyl wherein the alkyl is of 1-3 carbons. Z is R₁(m) and/or R₂(n) wherein at least one of R₁ and R₂ is an electron-rich substituent and m and m may be 1-4 and wherein R₁ and/or R₂ may be alkyl, alkoxy, aryl, aryloxy, aryloxyalkyl, amino, aminoalkyl, alkylaminoalkyl, arylamino, alkenyl, arylalkenyl, arylalkylaminoalkyl, carboxyalkyl, hydroxy, halo, alkenyl, alkenyloxy, herein any alkyl has 1-8 carbons, alkenyl has 2-8 carbons, halo is chloro, fluoro or bromo and aryl is a ring system of 1-3 rings. Preferred electron-rich substituents are chosen from moieties containing unsaturated ring systems (such as phenyl, phenoxy and naphthyl), halo (preferably chloro, fluoro), trihalomethyl, alkoxy, alkenyloxy, alkylamino and aminoalkylamino groups wherein any alkyl has 1-8 carbons. However, when N is quinolyl, if the 2 position on the quinolyl ring is substituted with trihalomethyl and the 8 position is substituted with trihalomethyl or phenyl, the 6 or 7 position on the ring system must be further substituted with an electron-rich substituent such as halo or alkoxy. The preferred compounds of the invention require specifically a large substituent such as phenyl, phenoxy, naphthyl, trihalomethyl (particularly trifluoromethyl) or quinuclidinyl groups at the 2 position on the ring system. Any alkyl or aryl moiety may further be substituted with halo, hydroxy, amino, alkylamino, alkylamino groups having 1-4 carbons or alkenyl, alkenylamino of 2-4 carbons.

When N is a pyridyl ring, the 2 and 6 positions of the pyridyl ring must be substituted with aryl groups wherein aryl is phenyl or naphthyl. Compounds may be made by usual means. The following schemes are appropriate: ##STR1##

Particularly preferred compounds are of the formula: ##STR2## wherein q is 1-3, and, in N(alkyl).sub.(1 or 2), alkyl is of 1-8 carbons which may be substituted with halo or alkoxy and R₅ is H or alkyl of 1-4 carbons and, in formula II, wherein at least 1 of R₁ or R₂ is halo, haloalkyl, dihaloaklyl, trihaloalkyl or alkoxy.

or compounds of the formula: ##STR3##

wherein R₅ is H or alkoxy, J is a saturated nitrogen containing ring attached at the 2 position of ring J which may be substituted with halo or alkoxy and, in Formula IV, at least 1 of R₁ is halo, haloalkyl, dihaloaklyl, trihaloalkyl or alkoxy.

In compounds of formula I and II, the dialkyl compounds are active against micobacteriam, but not against gram negative organisms or bacteria. Hence, for broad spectrum activity, the compounds of wherein, in N(alkyl).sub.(1) are preferred.

Materials and Methods

Active agents of the invention were tested for activity against several infectious organisms. Testing for inhibitory effect against antibiotic-resistant organisms was accomplished in the following manner:

Media:

The strains were streaked on blood agar plates (trypticase soy broth containing 5% sheep cells). A single colony was isolated and grown in Mueller-Hinton Broth (MHB) as recommended by the national Committee for Clinical Laboratory Standards for rapidly growing bacteria. Candida species and related fungi were isolated in a similar manner on brain-heart infusion agar (BHI).

Susceptibility tests:

The antibiotic susceptibility profile of each strain was determined using standard microtiter dilution plates obtained from the Clinical Microbiology Laboratory at Ohio State University Hospitals. The Inocula were prepared by suspending a 4 hour log phase growth in MHB visually equal in turbidity of an 0.5 McFarland standard. Inocula were further diluted and added to microdilution trays to achieve a final density of approximately 1×10⁵ CFU/ml. The trays were incubated for 16 to 20 hours at 35° C. The highest dilution at which wells remained clear was considered to be the minimum inhibitory concentration (MIC).

The MIC and minimum bacterial concentration (MBC) of the strains to the active agents were determined by two-fold dilutions in Mueller-Hinton broth. Susceptibility tests for ATCC-obtained microorganisms and clincal isolates of gram positive bacteria including methicillin-susceptible and resistant Staphylococci, Streptococci, Pneumococci and gram negative bacteria, including Enterobacteriaceae, Pseudomonas, Hemophilus and Neisseria, were performed in microtiter plates as described above. The MIC and MBC were determined after 48 hours incubation at 35-37° C. A sample of 0.01 ml was taken from each clear well at the MIC end-point and streaked on trypticase soy agar plates. After 24 hours incubation, the number of colonies was counted. The amount of the agent required to kill 99.9% of the bacterial inoculum was determined as the MBC. Susceptibility tests for ATCC isolates of Candida and other fungi were performed in BHI broth according to the NCCLS method. Two ml of MHB containing serial dilutions of the agents compounds were added to 13×100 mm tubes. An inoculum of 0.1 ml (prepared as described above) was then added to each tube. The final inoculum was approximately 1×10⁻³ to 1×10⁻⁵ CFU/ml. The tubes were incubated at 35° C. in ambient air and read at 24 hours. The highest dilution at which the tubes remained clear was considered to be the MIC.

The MBC was determined as follows: After 48 hours incubation, tubes without visible growth were vortexed. A sample of 0.01 ml was taken from each tube and streaked on trypticase soy agar plates. After 24 hours, incubation, the number of colonies was counted. The amount of agent required to kill 99.9% of bacterial inoculum in the inoculum was determined as the MBC. Susceptibility tests for Mycobacteria were performed according to standard methods at the national Institutes of Health.

Compounds of the invention were dissolved in 1 ml of methanol and stored in aliquots at -70° C. They were diluted in Mueller-Hinton broth for final screening. Compositions were tested in 0.1 ml volumes by serial dilution in microtiter plates against Staphylococcus aureus methicillin-sensitive ATCC 29213 and the methicillin-resistant wild type T67738, as described above. The T67738 was resistant to most antimicrobial drugs, including ciprofloxacin.

The most active compounds were studied further by time and dose-related killing curve analysis using large inocula (1×10⁷ CFU/ml).

The lipid solubility of these compounds should permit the drugs to enter into cells and the central nervous system. The compounds would also be absorbed orally.

The dosage and method of administration will depend on the location of the infection, the condition of the patient and the availability of professional supervision. Methods of administration include parenteral, oral, buccal, nasal or endotracheal routes. The active agents may be administered as sprays. For nasal administration, the active agent may be delivered as a powder that is snorted. Inclusion complexes such as cyclodextrin inclusion complexes are appropriate compositions and would be particularly useful for buccal administration of these active agents.

The compounds of the invention may also be administered topically by any means, including by rectal route. Suppositories, solutions for use as retention enemas, and creams or jellies are appropriate carriers for use in rectal administration.

Compounds of the invention may be applied to the skin or mucosa, including the vaginal mucosa, using creams, jellies, suppositories, or solutions. The active agents of the invention may be delivered directly to the epithelial tissue topically. During surgery example of such use could involve the application of compositions containing the active agents of the invention to the exposed tissue and prosthetic devices. The compositions could be given by aerosol into the trachea or administered in mist along with other agents used in respiration therapy.

The compositions of the invention may also be used prophylactically to protect from infection by pathogenic organisms.

Dosage forms containing 25 to 1000 mg for administration by mouth are appropriate.

The concentration required to provide benefit was studied. The results may be seen in Table I
